Blowing Fuses I have a 1993 - 2000 Panasonic "the Genius" Microwave, and it has suddenly started blowing the fuse on the power supply card. I have replaced the 8A fuse with a 10A fuse, but that still blows. It was working fine up until yesterday, Please advise me as to what could be the problem, and how to rectify it. Regards Lyall Clifton

Why does my Sharp Carousel convection microwave keep blowing fuses ?


I am wondering which fuse is blowing?
There are at least two fuses fitted internally and in the UK at least another fitted in the plug of the supply lead.

It isn't wise for an unqualified person to replace the internal fuses of a microwave even if it is switched off as there is a capacitor inside that is capable of storing a dangerous amount of energy.

The reasons why a fuse blows is either because there is a poor connection close by that is generating a lot of heat or the the fuse rating is incorrect or of the wrong type (quick-blow instead of slow-blow) or the appliance is consuming more current than it should be.

Microwave ovens have a fairly simple working principle and there aren't many things to go wrong. When things do start to go wrong or components become tired it is usually translated into a loss of efficiency that can be measured by how long it takes to boil a measured quantity of water, for instance.
Periodically timing a measured quantity of water to boiling point is a good way to monitor the performance of a microwave and when efficiency falls significantly take it to the service shop before something destroys itself and causes more damage.

In my limited experience the magnetron could be failing but the internals of a microwave should remain a mystery to the unqualified.
I hope this helps a little.

How do I find the fuses in Microwave


Mainly there are three/four fuses in Microwaves depend to maker.
First one to be checked it is on plug about 13A in cable out side microwave
Second one for power supply usually comes 10A located in terminal board of cable supply in side microwave if you follow the cable.
Third fuse i think about 5A for high voltage it located usually on wire connected between transformer and capacitor.
Fourth some Microwave have third one on the control board located behind switch panel.

now.

if the second fuse is blowing immediately after starting microwave that usually mean one or more of the following need to be replaced

1- diode
2- HV. capacitor
3- magnatiron

Which only can replaced by skill technicians

THANK YOU.

I have a J HP60G 002 GE Microwave (older)keeps


If it blows the line fuse instantly when you push start.... it is either a shorted HV capacitor or shorted monitor switch.... most likely.

Our Panasonic Genius 1200w microwave stopped working all of a sudden. It's completely dead - even the front panel. Is it worth fixing?


It could be just the fuse and fixed for a couple bucks. Only way to know is open it up and check it. Eric

Blowing 25 amp fuses


In that case the outlet your using is pushing out too much electricity. Try calling your local electric company for help or a professional electric repair man.

Keeps blowing fuses


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

Here is a link you or someone you know can use to test it, but please read the safety info:

You can order Panasonic parts from Tritronics here or by calling 866-779-5835, but if you don't find what you're looking for there, try here.
